The error in your logs is:

Nov 9 19:25:47 ubuntu ubiquity: grub-install: warning: Cannot set EFI variable Boot0000.
Nov 9 19:25:47 ubuntu ubiquity: grub-install: warning: efivarfs_set_variable: writing to fd 7 failed: Invalid argument.

Nov 9 19:25:47 ubuntu ubiquity: grub-install: error: failed to register the EFI boot entry: Invalid argument.

Do you know of a reason that Ubuntu would be unable to write to these firmware variables, such as a BIOS security setting?
